After the meet I went to the doctor to chat about what might be wrong. I was weak, a little achy, but nothing too strange... both of my kids had been sick so I thought I might just be fighting something... but then I started piecing together some clues that made me start down a new rabbit hole on the google.
I had been getting a little light-headed when getting up from my chair, which isn't that odd since my blood pressure is naturally so low, but it was something I remembered being frequent when I first started the new diet and was running a lot that I hadn't really experienced in a while. My leg cramps had also returned with a vengeance over the last few weeks... I should have seen all of the signs that I wasn't paying enough attention to electrolytes, but I had been busy enough with work that I just didn't take the time to think it through.
The other symptoms were new. At the meet I had been joking with a few people that I must have added all of my muscle in my legs because my TYR AP-12 was extra tight, which is strange because it is a pretty worn suit. My jeans also felt tight. Also, I have always twitched while falling asleep, but recently it had gotten out of control-- it was lasting all night and was at the point where my wife was making me sleep on the couch.
|My dreams were awesome but I can understand why she wanted it to stop.|
By the time I got to the doctor the next week I had noticed that my ankles were swollen enough that you might have guessed I was pregnant.
|It took like 4 hours to get my tech suit on.|
Here's the list:
- Leg cramps at night had returned to the level they were when I first started the diet.
- Lightheaded when I got out of the chair.
- Twitching was worse and lasted through the night.
- Legs, particularly ankles, were swollen.
- Weak, with aches.
Well, here's what it boils down to:
- I left my normal diet routine. I had to travel during the week and was left to eat at restaurants, leaving my normal routine along with electrolyte supplements out of the picture. The normal foods I eat that make me feel great were not available. Bad idea for meet week. The LCHF diet is kind of like a diuretic, as without the abundant glucose bonding to water, we don't retain as much. We have to replace electrolytes more frequently.
- I experimented with baking soda supplementation. There is a lot of recent research showing that it might actually be legit.
As far as the routine is concerned, I just wasn't smart enough to think ahead and plan for my abnormal week. My bad. The baking soda though, had never been anything but good in the past. If the idea is to ward off the acidity that interferes with muscle fiber contraction at the end of a race, lowering your pH at race time might be a pretty good bio-hack. I had been reading up quite a bit on it, and I think that they need to add an asterisk to the research. I think the diuretic effect of this diet makes me need to be a little more cautious with the sodium bicarbonate than the average racer.
As I was looking up symptoms of electrolyte issues, I discovered that all of the stuff on my list could be attributed to low potassium. I have always monitored this pretty closely and had become a little lax, sure. But, then I stumbled upon a post on reddit that implied that baking soda supplementation can cause hypokalemia (low potassium) by itself. This, I believe, is why my symptoms were so much more pronounced than ever before. I had already been on the edge of a problem, and the bicarb opened the floodgates.
This might seem like a pretty involved excuse for not swimming fast, but that is not my intention. (As a coach I have heard some pretty elaborate excuses as I am sure you can imagine.) It is more of a cautionary tale. Self-experimentation means you might have to become a little bit of a detective. My doctor didn't know what to tell me. I had to research it and figure out why I didn't seem to have ankle bones anymore and why I had become a Mexican jumping bean at night. I just hope this tale of electrolytes gone bad helps anyone experimenting with keto to watch out for issues that need to be addressed!
Once I realized what was going on I added some potassium rich foods back into my diet, like spinach and avocado. I took a few extra of the 99mg potassium gluconate supplements I normally use, and I started using nuun tablets a little more frequently. Of course, I also did not touch the baking soda. By the end of the week my ankles looked human, and I hit a 2:07 200 breast in a time trial just to make myself feel better and redeem the lousy 2:09 I did the week before. All is good now and I am back to training after a short break.
How did your season ending meet go?
